A data providing system utilizes the resources of a digital broadcast and a network efficiently so as to provide data for a great number of users at high efficiency. The system includes a server station for communicating with terminal devices individually via the network, and a host station for transmitting the same data to all the terminal devices all at once in real time by the digital broadcast. Individual data and light-load data are handled by the server station, and the information such as load data, which should be shared by the terminal devices, are handled by the host station.
